The present disclose relates to a wireless charging device for charging a portable electronic device. The wireless charging device includes a charging panel, a transmitting unit and at least one adsorbent unit. The charging panel includes a first surface and a second surface opposite to the first surface. The first surface supports the portable electronic device. The charging panel defines a through hole through the first surface. The transmitting unit includes a coil for generating electromagnetic signals. The adsorbent unit extends through the through hole of the charging panel and adsorbs the portable electronic device.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A wireless charging device for charging a portable electronic device, comprising: a charging panel comprising a first surface and a second surface opposite to the first surface, the first surface for supporting the portable electronic device, the charging panel defining a plurality of through holes extending through the first surface; a transmitting unit comprising a coil electrically connecting to a power source for generating electromagnetic signals transmitted through said first surface for charging the portable electronic device; and a plurality absorbent units, each of the absorbent units comprising an absorbent portion passing through the through hole of the charging panel for adsorbing the portable electronic device thereto, a free end surface of the absorbent portion for adsorbing the portable electronic device being coplanar with the first surface of the charging panel.
2. The wireless charging device of claim 1 , wherein the power source supplies the wireless charging device with power for operating the transmitting unit.
3. The wireless charging device of claim 1 , wherein the absorbent portion is made of rubber.
4. The wireless charging device of claim 1 , wherein the absorbent portion is a vacuum suction.
5. The wireless charging device of claim 1 comprising two absorbent units, wherein each absorbent unit comprises a plurality of absorbent portions.
6. The wireless charging device of claim 5 , wherein the two absorbent units are arranged on two opposite sides of the transmitting unit.
7. The wireless charging device of claim 1 , further comprising a holder for supporting the absorbent unit.
8. The wireless charging device of claim 1 , further comprising two slippery mats arranged on two opposite ends of the first surface of the charging panel.
9. The wireless charging device of claim 1 , further comprising a bottom cover, the bottom cover and the charging panel cooperatively defining a cavity for receiving the transmitting unit and the absorbent unit.
10. The wireless charging device of claim 9 , wherein each absorbent unit is fixed on the bottom cover by a holder.
